11 Claims.

This invention relates generally to a combined angle plate and clampingdevice and more particularly to a combined angle plate and clampingdevice which has novel means for quickly attaching and detaching amovable jaw.

Base plates and angle plates now on the market are quite expensiveinasmuch as T-slots are formed crosswise of the plates which requiremuch time and expense in milling operations. Vises now have a movablejaw with a screw and nut for moving same requiring considerable time tomove a jaw to a given position. The capacity of these Vises is limitedbecause of the limitation of the opening thereof. It is diicult tosquare up a workpiece in present vises.

It is, accordingly, an ob;l ect of my invention to rovide a combinedangle plate and clamping device for toolroom use which is simple inconstruction, economical in cost, economical in manufacture, and simplein operation.

Another object of my invention is to provide a combined angle plate andclamping device wherein the slots in the angle plate comprise spacedcross slotted cylindrical apertures in which a depending angle member ofa movable jaw slides for fastening same to said angle plate atpredetermined distances from the vertical plate thereof.

Another object of my invention is to provide in a clamping device amovable jaw for disposal .xy

in a minimum of time at different xed distances from a fixed jaw.

Another object of my invention is to provide a movable jaw on a combinedangle plate and clamping device, the movable jaw being movablelongitudinally and vertically.

Another object of my invention is to provide a combined angle plate andclamping device in which two jaws may be utilized.

Another object of my invention is to provide a combined angle plate andclamping device wherein rectangular and round workpieces may beaccommodated. f

Another object of my invention. is to provide a combined angle plate andclamping device which has provisions for attaching a clamp thereto forsecuring a round workpiece or a comparatively large workpiece externallythereof.

Another object of my invention is to provide a combined angle plate andclamping device so constructed that it may be manufactured in a minimumof time.

Other objects of my invention will become evident from the followingdetailed description,

taken in conjunction with the accompanying drawings, in which Fig. 1 isa perspective view of my novel combined angle plate and clamping device;

Fig. 2 is a perspective view of my novel angle plate with a round piececlamped thereon;

Fig. 3 is an enlarged fragmentary side elevational view of the fasteningmeans for support for my novel movable jaw;

Fig. 4 is a fragmentary sectional view of the clamping jaw and the leadscrew and shaft connected thereto;

Fig. 5 is a side elevational View of my novel angle plate with a flatpiece in position to be clamped to the outer side thereof; and

Fig. 6 is a side elevational view of my novel angle plate with a roundpiece clamped therein.

Referring now to the drawings, I show in Figs. l to 6 inclusive an angleplate I having a Vertical face 2 and a horizontal face 3 at right anglesto each other. The vertical face 2 forms the xed jaw of a clampingdevice as Will be hereinafter described. The horizontal face 3 hastransverse slots 4 spaced from each other and from the face 2 of theangle plate I, the slots 4 terminating in cylindrical, transverselyextending apertures 5. The slots 4 are cut tangent to the side of theapertures 5 adjacent the vertical face 2. It will be seen that it is asimple machining operation to drill the apertures 5 and then cut a slot4 from the top face 3. The cost of this operation is many times cheaperthan forming a T-slot. The angle plate I has a corner thereof cut awayat forty-five degrees to form a beveled surface 6 to accommodate a jawof a parallel jaw clamp 'I to secure a round piece 9 on the angle plateI as shown in Fig. 2.

A U-shaped member I0 has an L-shaped depending portion I2 so that it maybe secured to the angle plate I by merely sliding the depending portionI2 into any of the slots el as shown in Figs. 1 and 3 to dispose it inany desired position spaced from the face 2 of the angle plate I. Avertically slidable H-shaped block I3 has grooves I4 formed on oppositesides thereof so that it slides vertically between opposed legs I5 ofthe U-shaped member I 0. The block I3 has a longitudinally extending,threaded aperture I5 for threadably receiving a lead screw Il having ajaw I8 mounted on the end thereof adjacent the face 2 of the angle plateI. A knurled handle I9 is formed on the end of 'the screw I'I oppositeto the jaw I8. The handle I9 has radially extending apertures'ISatherein for the insertion of a small bar to rotate the 'screw Il. The

block I3 also has a longitudinally extending aperture 2U disposed belowthe threaded aperture I6 and parallel therewith, the aperture 2lislidably guiding a rod 2I. A plate 22 is secured to the end of the rod2I by a screw 23 and it has a bifurcated end 22a nested in a peripheralgroove (not shown) on the lead screw I1. The rod 2I and the lead screwI1 have reduced end portions 24 and 24a which extend into parallelrecesses 25 and 25a in the jaw I8 whereby the jaw I8 is held in avertical position. The jaw I8 has a projecting portion 26 on one endthereof to engage a workpiece as shown in Fig. 1. The block I3 may bereversed so that the projecting portion 26 may be on the lower portionof the jaw I8. various positions.

In the operation of my novel device as an angle plate, the movable jawsupporting member I is removed from the angle plate I. When it isdesired to use my novel device as a clamping device to hold a workpieceagainst the face 2 of the angle plate I as in Fig. l, the dependingportion I2 of the member I0 is inserted into the desired slot II inaccordance with the thickness of the workpiece to be disposed againstthe face 2 of the angle plate I. The vertically slidable block I3 isthen disposed between the legs of the U- shaped member I0 in the desiredvertical position, as shown in Fig. l, and the handle I9 on the leadscrew I1 is rotated until the projecting portion 26 of the jaw I8engages a workpiece disposed against the face 2 of the angle plate I.The slidable block I3 may be disposed in any vertical position in theU-shaped member Ill and the U-shaped member I0 may be moved laterally toany desired position before the projecting portion 26 of the jaw I8enga-ges the workpiece. This is determined in accordance with the shapeand height of the workpiece. When the vertical height of the workpieceis relatively small, the slidable block I3 is reversed so that theprojecting portion 26 of the jaw I8 is on the lower side thereof. Itwill be evident that my novel combined angle plate and clamping devicemay n.

be set up quickly and it will hold a workpiece of maximum size ascompared with present vises now on the market. In present conventionalvise jaws, there must necessarily be play in the movable jaw whichresults in the engagement of a workpiece by one side of the movable jawin many instances, thereby causing uneven clamping. My device alwaysproduces square even clamping.

A comparatively large workpiece 3l may be attached to the outer or backface 30 of the angle plate I in the position shown in Fig. 5 by theparallel jaw cla-mp 'I shown inFigs. 2 and 6. The round workpiece 9 maybe secured on the angle plate I by the parallel jaw clamp 1 as shown inFigs. 2 and 6 with the one jaw of the clamp 1 engaging the roundworkpiece 9 and the other jaw of the clamp 'I engaging the cut awa-yportion Bon the lower corner of the angle plate I. My'angle plate is:particularly suitable for securing a round workpiece with a clamp 1 sothat the end of the round workpiece 9 may be worked upon with Vthe angleplate I sitting on its side.

My novel angle plate I may accommodate two or more U-shaped membersI'ac'cording to the width of the face 3 .-thereofso that two or moreclamping jaws I8 may be provided to hold a workpiece squarely againstthe vertical face 2 of the angle plate I.

The block I3 is also movable vertically to It will be evident from theforegoing description that I have provided a novel combined angle plateand clamping device particularly useful for close tolerance work, suchas for use in a toolshop, whereby it may be used as an angle plate or asa clamping device which may be set up in a minimum of time, which hasnovel attaching means for a movable jaw of a clamping device, and acombined angle plate and clamping device which is extremely simple inmanufacture and economical in cost.

Various changes may be made in the specific embodiment of my inventionwithout departing from the spirit thereof or from the scope of theappended claims.
